Record #189540:

Stable isotope food-web analysis and mercury biomagnification in polar bears (Ursus maritimus) / Travis W. Horton, and 4 others.

Title: Stable isotope food-web analysis and mercury biomagnification in polar bears (Ursus maritimus) / Travis W. Horton, and 4 others.
Author(s): Horton, Travis W.
Date: 2009.
In: Polar Research. (2009.), Vol. 28(3) (2009)
Abstract: Presents stable carbon and nitrogen isotope ratios, and mercury concentrations, for 26 late 19th century and early 20th century polar bear (Ursus maritimus) hair specimens, collected from catalogued museum collections. Data elucidate relationship between high-latitude marine food-web structure and mercury concentrations in polar bears. Carbon isotope compositions of bear hairs suggest that bears derive nutrition from coupled food-web channels, based in pelagic and sympagic primary producers, whereas nitrogen isotope compositions indicate that bears occupy greater than fourth-level trophic positions.
